184 Masterpiece 4 • PneumADDic II
For the PnuemADDic II you will need to build a total of eight potentiometer bricks,
therefore you will need the following supplies:

■ 16 1x2 LEGO electric plates (you can get larger plates and cut them into 1x2 if
you want)
■ 16 1x2 standard LEGO plates

■ 8 2x2 standard LEGO plates
■ 8 10K Ohm potentiometers (10K means 10,000 Ohms, a measure of resistance)

■ 1 foot of wire (standard copper telephone wire works well)
■ Goggles

■ Xacto knife
■ A strong adhesive (Krazy Glue works well)
■ Soldering pen

■ Solder

Potentiometer Brick Step 0
Cut a 1x2 electric plate as shown to provide access
to the underside electrical contacts. Solder one of
the legs of a potentiometer to the electric plate as
shown. Be careful not to melt the electric plate
with the heat from the solder pen.

WARNING

It is hard to cut such a small piece of LEGO safely. It is recommended that you
insert the 1x2 electric plate into the back of a larger plate. The larger plate will
be easier for you to hold, and it will hold the electric plate. Be careful not to cut
yourself.
